Been looking at some wide angle lenses for my DL, and been noticing that while any truly wide angle lense is awfully expensive (yeah, I know, photography is an expensive hobby), the ones with big aperatures are noticeably cheaper than those with small aperatures, numerically speaking (i.e a 1:2.8 is more than one with 1:3.5).
I know the aperature controls how much light enters the lens (along with shutter speed), and a smaller aperature number means more light can enter. Other than making it easier to get an in-focus picture while hand holding the camera, what other reason would I want to get a smaller number aperature? Considering 90%+ of my photography is done of non-moving subjects, and using a tripod, can I compensate with a slower shutter speed, or longer exposures? eric -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
